IMCA 500 cfm engine option, what heads?!

[drivingexcitement]

So is stockcar5 still running a 350 Carb motor? And is parrots prediction of the spec motor still true?

[stock car driver]

Lol.. Stock car 5 went to a 360 in 12 and won around 20 races... Not sure about this year, never saw his name anyplace but did notice he won a championship at one track on a sheet I saw.

Good info! So if you had to run a 500 cfm and had no head or cubic inch rule, are 406 & 421s the best engine to use with the limited carburetor?

yea i switched in early 2012 after getting second all the time to a couple of 360's lol. on the 1/2 mile tracks it's amazing how much better they are. and jeff is right. 20 wins and 5 track championships in the last 2 years.

What kind of HP are the spec engines making?

[stockcar5]

380-390hp 400-420tq is a good one where i dyno.
